7 Claims.

This invention relates to improvements in shaker conveyors, and more particularly to an adjustable trough supporting and aligning means for a. shaker conveyer trough line, adapted to be secured between a mine floor and roof to hold the trough line in longitudinal and transverse alignment.

The principal objects of my invention are to provide a new and improved adjustable trough supporting and guiding means for a shaker conveyer trough line including a plurality of spaced apart supporting jacks having trough supporting rollers mounted thereon in such a manner that the trough line may readily be aligned and held in both vertical and horizontal alignment during operation of the conveyer, when the jacks are in various angular positions with respect to each other, together with a simple means for adjusting the rollers and their supporting shafts along the jacks.

My invention may be more clearly understood with reference to the accompanying drawing wherein:

Figurel is a view in side elevation of a part of a shaker conveyer trough line, supported by trough supporting means constructed in accordance with my invention;

Figure 2 is an enlarged transverse sectional view taken through the trough line, showing certain parts of one jack broken away and certain other parts thereof in transverse section;

Figure 3 is an enlarged fragmentary isometric view, showing one of the trough supporting jacks and the supporting connection from this jack to the conveyer trough; and

Figure 4 is an enlarged detail view showing cer tain details of. construction of the adjustable supporting connection for the trough supporting roller on its supporting jack.

Referring now to the embodiment of my invention illustrated in the drawing, a shaker conveyer trough line generally indicated by reference character I0 is shown as being supported and guided on a plurality of pairs of spaced apart jacks II, II, interposed between a mine roof and floor. Said shaker conveyer trough line includes a plurality of trough sections I2, I2 connected together at their ends by connecting bolts I3, I3 extending through abutting eye pieces I 4, I4. Said trough line is reciprocably driven by the usual type of reciprocable drive mechanism (not shown), in such a. manner that reciprocable movement of said trough line will cause material to move therealong in one direction.

The jacks II, II are of a usual construction,

engaging member 20 on the upper end thereof,

is adapted to extend within said sleve. Said shaft is telescoped within or extended from said sleeve by means of a wing nut or threaded member 2I threaded thereon and having oppositely extending hand grips 22, 22. Said threaded member is adapted to rest on the collar I8 and a retaining member 23 is herein shown as projectin downwardly from one of the hand grips 22 and extending inwardly of said collar, to prevent upward lifting movement of said threaded member with respect to said collar.

The trough sections I2, I2, as herein shown, are each provided with longitudinally extending channeled guides adjacent opposite sides thereof and intermediate the ends thereof. Said guides, as hereinshown, consist of a pair of vertically spaced facing angles 24, 24, 'with their vertical legs disposed inwardly. Each pair of said angles is secured to opposite side of said trough section by means of a pair of parallel spaced straps 25, 25, secured to the outer sides of the upper flared portion of said trough section in any suitable manner, such as welding. Opposite guides are secured together, to maintain rigidity of said guides, by means of parallelspaced connecting members 25, 26, secured to the bottom of said trough section and connected to opposite lower angles at their ends.

Rollers 29, 29 are provided to support the trough section I2 on the jacks II, II. Said rollers are each mounted on a shaft 3E! and the upper angles 24, 24 ride thereon, the lower angles serving to prevent upward lifting movement of said trough section. Said shafts, as herein shown, are

mounted in sleeves 3I, 3|,which are mounted in the open ends of a U-frame 33, which serves to hold said shafts rigid with respect to each other and in aligned relationship, to permit alignment of the trough sections where the bottom is uneven, or when the jacks are in various angular relations with respect to each other.

Each sleeve 3I loosely extends through a strap 34, projecting from the lower end of an adjusting member 35, which is slidably mounted on the sleeve I6 of the jack II. The clearance between said strap and sleeve is sufficient to permit a substantial amount of angular movement of said jack with respect to said shaft, and thus permit accurate alignment of the trough sections, without binding, when the jacks are at various angular positions with respect to each other and. with respect to said shafts, as in cases where the bottom is uneven.

A U-shaped clamping member 36 is provided to secure each shaft 30 and adjusting member 35 in position along the sleeve It. The ends of said clamping member extend along said opposite sides of the strap 34 and are of a fishtail formation to firmly engage the sleeve 3 l Said clamping member is tightened against said sleeve to engage said sleeve with the sleeve [6 and rigidly hold the sleeve 3! and the adjusting member 35 in position on the jacks ll, by means of a nut 31 threaded on the outer end of a stud 38 and engaging the outside of said clamping member. The opposite end of said stud is threaded within the strap 34.

Referring now in particular to the means for adjustably moving the adjusting members 35, 35- along the sleeves l6, l6 and jacks H, H, said jacks are each provided with a pair of spaced apart projecting brackets 39, 39, between which is mounted a rod' 4'01 Said rod extends through a pair ofspaced apart abutments 43, #3 projecting from the adjusting member 35, and through a friction grip lifting member 44, which is disposed between said abutrnents and serves to lift said elevating member or permit it to be loosened. A suitable hand lever 45 is pivotally mounted on the lifting member 44 to clamp certain friction means (not shown), mounted within said elevating member, with the rod 43-, and move said lifting member upwardly along said rod. Said rod and liftin member are of a construction similar to the well-known form of automobile type friction bumper jack, and are not part of my present invention so need not herein be shown or described in detail.

It may be seen from the foregoing that the shafts 3U, 30 and rollers 29, 29' may be adjustably moved along the sleeves I6, I 6 by the lifting members 44, 44, to adjust the conveyer trough line It in a transverse or vertical direction, and that since substantial clearance is provided between the sleeves 31, 3| and the straps 3'4, 34, said adjusting mechanism is effective andsaid shafts may be rigidly held in position when the jacks II, II are parallel spaced or are angularly positioned with respect to each other. It may likewise be seen that the independent adjustment of said shafts along said sleeves permits ready adjustment of the trough line, and that the rollers 29, 29 engaging within the channelled guide formed between the spaced apart angles 24, 24 prevent upward lifting movement of the trough line with respect to said jacks, and the ends of said rollers engaging the vertical legs of said angles serve to hold said trough line in longitudinal alignment.

While I have herein shown and described one form in which my invention may be embodied, it will be understood that the construction thereof and the arrangement of the various parts may be altered without departing from the spirit and scope thereof. Furthermore, I do not wish to be construed as limiting my invention to the specific embodiment illustrated, excepting as it may be limited in the appended claims.
